AWNING.

Appiicafrion inea Aprn 1e, 192s. seriar No. 102,378.

The object of my invention is to provide new and improved means formounting awnings, and also for holding them in` normal extendedposition. Vith these objects in view my invention consists in thematters hereinafter described and pointed out in the appended claims. Kv ln the accompanying drawing, vFigure 1 is a perspective view of anawning embodying the features of my invention and mounted in positionfor use, only part of the window-casing being shown; Fig. 2 is a detailside view with parts broken away; Fig.V 3 is a detail frontview of theframe-fixture with parts of the frame in section on the line 3-3 in Fig.2; and Fig. 4 is a detail sectional viewon .the line4-4'in Fig. 2.

The reference numeral 1 .indicates a spring-roller mounted in suitablebrackets 2 secured upontlie outside of a windowcasing 3, usually at ornear the line whereV the upper and lower sashes meet. The awning-cloth,consisting of a suitable length of canvas or other material, isconnected intermediate its ends to the roller so that its upper andlowersections 4 and-5l will wind thereon. The lower section 5 isattached at its free end to the cross-piece of a bowed metallic frame-6,which is pivotally mounted at its endson the window-casing, andthe uppersection 4 has a head-rod 7 to which an operating cord 8 is connected andpassed over one or more pulleys 9, according tov whether it is extendeddown on the outside ofthe window or through the window-casing into theroom.k The freeend of the cord may be suitably fastened either insideVor outside the window to hold it in any desired position. Vhen the cordis drawn up the upper section 4 of the awning-cloth is extended or drawnupwardly tothe position shown in Fig. 1, the roller is revolved to placeits spring section 5 of the cloth, and the frame 6 swings down bygravity to its extended position. lVhcn the cord is released thespring-roller automatically winds up thesections of the awning cloth towithdraw them from their extended positions and to swing the frame 6 upto positionalongside the window-casing below the roller. v

The frame Gis detachably securedto the window-casing by devices whichpermit it to be attached and detached without swinging the frame downbelow its normal extended position. 1n this type of awning as hereundertension andunwind the lower tofore constructed hooks on the free ends ofthe frame engaged supports on the'casing, and in order to preventdisengagement of the hooks by the wind blowing the. awning upwardly itwas necessary to extend or prolong the ends of the hooks around theirsupports, and consequently the hoolrs'conld be engaged thereon only whenthe frame was swung down below its normal extended position to permitthe hooks to pass onto their supports from above. This is objectionableas it requires unrolling the awning-material which *isy then cumbersomeand difficult to handle.L I obviate this objection by providmgthe frame6 with endeyes or loops 10 which pivotally` engage opposite pintles 11extending laterally from brackets 12 on thev casing.V The vfree ends ofthe pintles are reduced, and gravity latches 18 of approximately thesame diameter as the pintles arepivoted thereon.intermediate their endsbut offset from their centers as shown at 14;

when the latches are turned to align with the pintles theloops 10 may beeasily slipped on or' off'the latter, and when the latches arereleasdthey will turn by gravity to position tobloclr the loops andholdthem on the pintles. This construction simplifies the in-vstallation and removal ofthe awning, as it may be put up or taken downwhile thek cloth is wound on the roller and the frame is in one of itsnormal positions.

The frame 6 is held in its extended position by a friction lock` whichhas sufhcient grip to prevent the lower section of the awning beingblown upwardly by the wind,

but wlnch readily yields to the, superiorv strength of the spring of thelroller when the cord is released to permitthe latter to revolve. In theform here shown, annular metallic collarsl are slidably'mounted on theside arms of the frame G, and each collar is provided with upwardlyprojecting ears 16 in which one end of a link 17 is pivoted, the otherend ofthe link having a downwardly'opening hook A1,8 to vengage the iookcross-pin 19 of a jaw-hinge i2() on the casing Y above the bracket 12.Each collar is provided with a chamber in which a friction ball 21 islocated and held by an expansion spring 2Q in contact with theassociated side arm ofthe frame 6, which is provided with a recess ornotch 23 so located that the ball engages it when the frame is in itsextended position. inplace by a cap 249 and the pair of springs Eachball and spring are heldV Ii i) i'or each :trame is ot less strengththan the roller-spring. lVhen the traine and awning` are extended by thecord 8 the balls engage the notches and hold the lower section 5 against'flappingg or being blown upwardly by the wind. 'frvhen the cord isreleased the superior strength ot' the roller-spring overcomes theresistance of the relatively weaker springs 22 and the roller winds upthe awning' and swings the trame G upwardly. The links move the collarsinwardly and outwardly on the sides ot' the iframe as tlie'latter swingson its pivots.

The pivotal bracket l2 and jaw-hinge 2() tor each side ot the `trame aremounted in line on a base which is screwed to the window-casingg eachbase and its bracket and jaw-'hinge constitute a unitary fixture on'which oneY side ot the traine G and its associated' link 1T aredetachably supported, andall' these parts can be 'positioned by merelyengaginT the hooks 1S with their pins i9 and the eyes 10 with theirpintles Il, and can be removed by merely disconnecting` .the same. Bothoperations can be accomplished with the awning-cloth wound on itsspring-roller. rl`h`c .tixtures provide a permanent assembly 'lor eachpair of brackets and jaw-hinges, it being understood that theconstruction and arrangement ot the various parts are the same on eachside of the awning.

I claim:

l. In a device of the class described, an awning, a swinging' iii-ametherefor pivotally mounted at its ends on a window-casing and having` arecess in oney oft its arms, a collar slidably mounted on said arm, alink pivotally connected to the collar and casing, a pressure member inthe collar in line with said recess when the trame 'is cxtenoed, and

a spring in the collar adapted to torce the pressure member intoengagement with the recess.

2. In a device oli the class described, an awning, a swinging` iframethere lor pivotally mounted at its ends on a window-casine` and having`a recess in one olf its arms. :i collar slidably mounted on said arm andhaving al chamber in line with said recess when the frame is extended, alink pivotally connected to the collar and casing, a ball inthe chamber,and a spring in the chamber adapted to force the ball into engagementwith the recess.

3. In a device of the class described, an awninpcomposed olf upper andlower sections connected to a spring-roller adapted to be revolublymounted on a window-casing;` a. swinging trame connected to the :treeend ot said lower sectionv and adapted to be pivotally mounted at itsends` on the window-casing and havinga recess in one ot its arms, acollar slidably mounted on said arm, a link pivotally connected to thecollar andcasing, a pressure member in the collar inline with saidrecess when the frame is extended, and a spring in the collar ot lessstrength 'than the springi in the roller and adapted to'iorce thepressure member into engagement with the recess.

fl. In a device of the class described, a swingingawning' trame havingan eye, a collar slidably mounted on the frame, a link pivotallyconnected at one end to the collar and having a downwardly opening hookat its other end, means to yieldingly hold the collar in position on thetrame when the latter is extended, and a unitary fixture foithe eye andhook ot the frame comprising a base, a pivotal support at the lower endof the base for the eye, and a pin at the upper end of the base t'or thehook.

5. In a device ol' the class described, a swinging awning` frame havingan eye, a collar slidably mounted on the trame, a link pivotallyconnected at one end to the collar and l aving a downwardly openingThook at its other end. and a unitary lixture for the eye and hook ot thetrame comprising a base constructed to be mounted on a window casing', alateral pintle at the lower end ot the base having a pivoted latch torthe eye, and a pin at the upper end ot the base for the hook.

In testimony whereof I hereto aliix my signature.
